The GRAVIMASTER dosing-blending system GM 10 is designed for efficient and accurate dosing/blen- ding of dry, free-flowing thermoplastic materials. The GM 10 is often used on injection moulding, extrusion, and blowmoulding machines where con- sistency and high quality of the finished product is required. Owing to the high and consistent dosing accuracy, the additive percentage can be reduced to lower tolerance limits without rejects or a loss in quality. The result savings in additives leads to a direct reduction in reduction costs. The GM 10 is suited for dosing of virgins (granu- late), free flowing regrind, master batch and/or additives. This blending system can be installed on a platform a support frame over or a stand next to the processing machine. Owing to simple removable parts a quick cleaning and material change is guaranteed. Components are dosed after each other into the weigh-bin, which is supported by an accurate weighing system. After weighing out the complete batch is dischar- ged into the mixing chamber and the horizontal mixer provides a consistent blend. A level sensor in the mixing chamber controls the complete blen- ding cycle. The GM 10 is an economic and user- friendly blending system.
